It's true. With only two matches so far, it's hard to say Manchester United are improving and Nistelrooy is a good coach.
And why did you even think Manchester United were improving? Their last match was against Chelsea, and I didn’t see anything special that they played in the match. We all know that the match will be a tough one for the two clubs, even if Manchester United are not in form, whenever they play against Chelsea, they are always playing well, and they played at home again, so they didn’t play anything special to me, and in their match against Leicester City, they played against a weak team, so we won’t call that an improvement. Let’s see how they will perform in their coming matches, before we going to conclude.
The thing is that Manchester United and Chelsea have created this long time rivalry such that when they face each other it always turns out to be a very tough game so that was actually what happened between Chelsea and Manchester United, it wasn't like Manchester United made any improvements, just because they played against Chelsea made them become more serious in the game. The only way Manchester United can be seen to have improved is how they can be able to perform more better than they were during the coaching time of ETH. I feel the acting coach Van Nistelrooy can't even do anything for the team now so the club's management should endeavor to choose a perfect coach for the team so that they won't always continue sacking their coaches all the time.
